[Patent Literature]
[0003] [PTL 1] the Publication of Japanese Patent No.
5443132 JP2010071226A discloses a co-rotating scroll compressor according to the preamble of claim 1.
[Summary of Invention]
[Technical Problem]
[0004] The co-rotating scroll compressor adopts a configuration in which a front end of
a spiral wall of each of the driving-side scroll and the driven-side scroll is supported
by a support member in some cases. In a case where such a configuration is adopted,
positioning pins that accurately position phases of the driving-side scroll and the
driven-side scroll around a rotation axis are provided in order to ensure engagement
of the spiral walls. When the positioning pins are pressed into the spiral walls,
however, the walls may be deformed to impair the engagement of the walls, which may
deteriorate performance and durability.
[0005] The present disclosure is made in consideration of such circumstances, and an object
of the present disclosure is to provide a co-rotating scroll compressor that is not
deteriorated in performance and durability when the walls are positioned by the positioning
pins.
[Solution to Problem]
[0006] To solve the above-described issues, a co-rotating scroll compressor according to
the present disclosure adopts the following solutions.
[0007] A co-rotating scroll compressor according to an aspect of the present disclosure
includes: a driving-side scroll member that is rotationally driven by a driving unit
and includes a spiral driving-side wall disposed on a driving-side end plate; a driven-side
scroll member that includes a driven-side wall corresponding to the driving-side wall,
the driven-side wall being disposed on a driven-side end plate and engaging with the
driving-side wall to form a compression chamber; and a synchronous driving mechanism
that transmits driving force from the driving-side scroll member to the driven-side
scroll member to cause the driving-side scroll member and the driven-side scroll member
to perform rotational movement in a same direction at a same angular velocity. A support
member is provided to a front end of at least one of the driving-side wall and the
driven-side wall in an axis direction. The support member is connected to the front
end by a positioning pin positioning a phase around a rotation axis, and rotates together
with the connected wall. The positioning pin is pressed into the support member and
is fitted into the wall in a non-pressed-in state.
[0008] The driving-side wall disposed on the end plate of the driving-side scroll member
and the corresponding driven-side wall of the driven-side scroll member engage with
each other. The driving-side scroll member is rotationally driven by the driving unit,
and the driving force transmitted to the driving-side scroll member is transmitted
to the driven-side scroll member through the synchronous driving mechanism. As a result,
the driven-side scroll member rotates as well as performs rotational movement in the
same direction at the same angular velocity with respect to the driving-side scroll
member. As described above, the co-rotating scroll compressor in which both of the
driving-side scroll member and the driven-side scroll member rotate is provided.
[0009] The wall and the support member are connected by the positioning pin. The positioning
pin is pressed into the support member while the positioning pin is fitted into the
wall in the non-pressed-in state. As a result, the positioning pin can be firmly fixed
to the support member, and fitting of the positioning pin does not cause shape deformation
of the wall. Since shape deformation does not occur on the wall, there is no possibility
of deterioration in performance and durability.
[0010] Note that "fitted in non-pressed-in state" indicates fitting at a degree at which
a pin hole is not deformed and enlarged due to fitting of the positioning pin and
the member is not deformed. Examples of such fitting include loose fitting.
[0011] Further, in the co-rotating scroll compressor according to the aspect of the present
disclosure, the positioning pin is provided at each of at least two positions around
the rotation axis.
[0012] Providing the positioning pin at each of the two positions makes it possible to determine
the position around the rotation axis.
[0013] Further, in the co-rotating scroll compressor according to the aspect of the present
disclosure, the driving-side scroll member includes a first driving-side scroll portion
and a second driving-side scroll portion. The first driving-side scroll portion includes
a first driving-side end plate and a first driving-side wall and is driven by the
driving unit. The second driving-side scroll portion includes a second driving-side
end plate and a second driving-side wall. The driven-side scroll member includes a
first driven-side wall and a second driven-side wall. The first driven-side wall is
provided on one side surface of the driven-side end plate and engages with the first
driving-side wall, and the second driven-side wall is provided on another side surface
of the driven-side end plate and engages with the second driving-side wall. The co-rotating
scroll compressor includes a first support member and a second support member. The
first support member is fixed to a front end side of the first driven-side wall in
the axis direction with the first driving-side end plate in between and rotates together
with the first driven-side wall. The second support member is fixed to a front end
side of the second driven-side wall in the axis direction with the second driving-side
end plate in between and rotates together with the second driven-side wall. The positioning
pin is provided between the first driven-side wall and the first support member and
between the second driven-side wall and the second support member.
[0014] In a case where the driven-side scroll member includes the first driven-side wall
and the second driven-side wall, the positioning pin is provided between the first
driven-side wall and the connected support member and between the second driven-side
wall and the connected support member.
[Advantageous Effects of Invention]
[0015] The positioning pin is pressed into the support member while the positioning pin
is fitted into the wall in the non-pressed-in state. Therefore, there is no possibility
of deterioration in performance and durability.

opening from which air (working fluid) is sucked in.
[0022] The motor 5 is driven by being supplied with power from an unillustrated power supply
source. Rotation of the motor 5 is controlled by an instruction from an unillustrated
control unit. A stator 5a of the motor 5 is fixed to an inner periphery of the housing
3. A rotor 5b of the motor 5 rotates around a driving-side rotation axis CL1. A driving
shaft 6 that extends on the driving-side rotation axis CL1 is connected to the rotor

[0023] The driving-side scroll member 70 includes the first driving-side scroll portion
71 on the motor 5 side, and the second driving-side scroll portion 72 on the discharge
opening 3d side.
[0024] The first driving-side scroll portion 71 includes the first driving-side end plate
71a and the first driving-side walls 71b.
[0025] The first driving-side end plate 71a is connected to the first driving-side shaft
portion 7c connected to the driving shaft 6, and extends in a direction orthogonal
to the driving-side rotation axis CL1. The first driving-side shaft portion 7c is
provided so as to be rotatable with respect to the housing 3 through the first driving-side
bearing 11 that is a ball bearing.
[0026] The first driving-side end plate 71a has a substantially disc shape in a planar view.
The plurality of first driving-side walls 71b each formed in a spiral shape are provided
on the first driving-side end plate 71a. The first driving-side walls 71b are disposed
at equal intervals around the driving-side rotation axis CL1.
[0027] The second driving-side scroll portion 72 includes the second driving-side end plate
72a and the second driving-side walls 72b. The plurality of second driving-side walls
72b each formed in a spiral shape are provided similarly to the above-described first
driving-side walls 71b.
[0028] The cylindrical second driving-side shaft portion 72c that extends in the driving-side
rotation axis CL1 is connected to the second driving-side end plate 72a. The second
driving-side shaft portion 72c is provided so as to be rotatable with respect to the
housing 3 through the second driving-side bearing 14 that is a ball bearing. The second
driving-side end plate 72a includes the discharge port 72d extending along the driving-side
rotation axis CL1.
[0029] Two seal members 16 are provided on a front end side (left side in Fig. 1) of the
second driving-side shaft portion 72c relative to the second driving-side bearing
14, between the second driving-side shaft portion 72c and the housing 3. The two seal
members 16 and the second driving-side bearing 14 are disposed to include a predetermined
interval in the driving side rotation axis CL1. For example, a lubricant that is a
grease as a semi-solid lubricant is sealed between the two seal members 16. Note that
only one seal member 16 may be provided. In this case, the lubricant is sealed between
the seal member 16 and the second driving-side bearing 14.
[0030] The first driving-side scroll portion 71 and the second driving-side scroll portion
72 are fixed while the front ends (free ends) of the walls 71b and 72b corresponding
to each other face each other. The first driving-side scroll portion 71 and the second
driving-side scroll portion 72 are fixed by the wall fixing bolts (wall fixing parts)
31 that are fastened to the flange portions 73 provided at a plurality of positions
in the circumferential direction. The flange portions 73 are provided so as to protrude
outward in the radial direction.
[0031] The driven-side scroll member 90 includes the driven-side end plate 90a that is located
at a substantially center in the axis direction (horizontal direction in figure).
The discharge through hole (through hole) 90h is provided at a center of the driven-side
end plate 90a, and causes the compressed air to flow toward the discharge port 72d.
[0032] The first driven-side walls 91b are provided on one side surface of the driven-side
end plate 90a, and the second driven-side walls 92b are provided on the other side
surface of the driven-side end plate 90a. The first driven-side walls 91b provided
on the motor 5 side from the driven-side end plate 90a engage with the first driving-side
walls 71b of the first driving-side scroll portion 71. The second driven-side walls
92b provided on the discharge opening 3d side from the driven-side end plate 90a engage
with the second driving-side walls 72b of the second driving-side scroll portion 72.
[0033] A first support member 33 and a second support member 35 are provided at respective
ends of the driven-side scroll member 90 in the axis direction (horizontal direction
in figure). The first support member 33 is disposed on the motor 5 side, and the second
support member 35 is disposed on the discharge opening 3d side.
[0034] The first support member 33 is fixed to the front ends (free ends) of the respective
first driven-side walls 91b on the outer peripheral side by first support fixing bolts
34, and the second support member 35 is fixed to the front ends (free ends) of the
respective second driven-side walls 92b on the outer peripheral side by second support
fixing bolts 36.
[0035] Positioning between the first support member 33 and the first driven-side walls 91b
around a driven-side rotation axis CL2 is performed by a positioning pin 40 that is
provided at an angular position different from an angular position of the first support
fixing bolt 34. More specifically, as illustrated in Fig. 2, one end of the positioning
pin 40 is inserted into a pin insertion hole 91b1 that is provided at the front end
of the corresponding first driven-side wall 91b, and the other end of the positioning
pin 40 is pressed into the first support member 33. The positioning pin 40 is fitted
into the pin insertion hole 91b1 of the corresponding first driven-side wall 91b in
a non-pressed-in state. In other words, the positioning pin 40 is fitted into the
pin insertion hole 91b1 at a fitting degree at which the pin insertion hole 91b1 is
not deformed and enlarged due to fitting of the positioning pin 40 and the corresponding
first driven-side wall 91b is not deformed.
[0036] Two positioning pins 40 are provided around the driven-side rotation axis CL2. Three
or more positioning pins 40 may be provided. In this case, it is unnecessary for the
third or more positioning pins 40 to perform actual positioning. Therefore, the third
or more positioning pins 40 become so-called dummy pins.
[0037] Note that positioning pins are similarly provided between the second support member
35 and the second driven-side walls 92b.
[0038] The shaft portion 33a is provided on the center axis side of the first support member
33, and the shaft portion 33a is fixed to the housing 3 through the first support
member bearing 37. The shaft portion 35a is provided on the center axis side of the
second support member 35, and the shaft portion 35a is fixed to the housing 3 through
the second support member bearing 38. As a result, the driven-side scroll member 90
rotates around the driven-side rotation axis CL2 through the support members 33 and
35.
[0039] The pin-ring mechanism (synchronous driving mechanism) 15 is provided between the
first support member 33 and the first driving-side end plate 71a. More specifically,
a rolling bearing (ring) is provided on the first driving-side end plate 71a, and
the pin member 15b is provided on the first support member 33. The pin-ring mechanism
15 transmits the driving force from the driving-side scroll member 70 to the driven-side
scroll member 90, and causes the scroll members 70 and 90 to perform rotational movement
in the same direction at the same angular velocity.
[0040] The co-rotating scroll compressor 1 including the above-described configuration operates
in the following manner.
[0041] When the driving shaft 6 rotates around the driving-side rotation axis CL1 by the
motor 5, the first driving-side shaft portion 7c connected to the driving shaft 6
also rotates, and the driving-side scroll member 70 accordingly rotates around the
driving-side rotation axis CL1. When the driving-side scroll member 70 rotates, the
driving force is transmitted from the support members 33 and 35 to the driven-side
scroll member 90 through the pin-ring mechanism 15, and the driven-side scroll member
90 rotates around the driven-side rotation axis CL2. At this time, when the pin member
15b of the pin-ring mechanism 15 moves while being in contact with the inner peripheral
surface of the circular hole, the both scroll members 70 and 90 perform rotational
movement in the same direction at the same angular velocity.
[0042] When the scroll members 70 and 90 perform rotational movement, the air sucked through
the air suction opening of the housing 3 is sucked in from outer peripheral side of
each of the scroll members 70 and 90, and is taken into the compression chambers formed
by the scroll members 70 and 90. Further, compression is separately performed in the
compression chambers formed by the first driving-side walls 71b and the first driven-side
walls 91b and in the compression chambers formed by the second driving-side walls
72b and the second driven-side walls 92b. A volume of each of the compression chambers
is reduced as each of the compression chambers moves toward the center, which compresses
the air. The air compressed by the first driving-side walls 71b and the first driven-side
walls 91b passes through the discharge through hole 90h provided in the driven-side
end plate 90a, and is joined with the air compressed by the second driving-side walls
72b and the second driven-side walls 92b. The resultant air passes through the discharge
port 72d and is discharged to outside from the discharge opening 3d of the housing
3. The discharged compressed air is guided to an unillustrated internal combustion
engine, and is used as combustion air.
[0043] The present embodiment achieves the following action effects.
[0044] The positioning pins 40 that perform positioning between the driven-side walls 91b
and 92b and the support members 33 and 35 are pressed into the support members 33
and 35 while the positioning pins 40 are fitted into the driven-side walls 91b and
92b in the non-pressed-in state. As a result, the positioning pins 40 can be firmly
fixed to the support members 33 and 35, and fitting of the positioning pins 40 does
not cause shape deformation of the driven-side walls 91b and 92b. Therefore, there
is no possibility of deterioration in performance and durability of the co-rotating
scroll compressor 1 because shape deformation does not occur on the driven-side walls
91b and 92b as described above.
[0045] Further, as illustrated in Fig. 3, a columnar collar 33b as a separate body may be
provided at a protruded part of the first support member 33, and the corresponding
positioning pin 40 may be pressed into the collar 33b. Since the collar 33b is provided
as a member separated from the first support member 33, the first support member 33
is easily machined. Further, a facing distance between the both scroll members 70
and 90 can be adjusted through adjustment of a height of the collar 33b. A similar
collar may be provided also on the second support member 35.
[0046] Further, as illustrated in Fig. 4, each of the positioning pins 40 may be pressed
into the first support member 33 by penetrating through the corresponding collar 33b.
In this case, each of the positioning pins 40 may be pressed into or loosely fitted
into a through hole of the corresponding collar 33b. A similar collar may be provided
also on the second support member 35.
[Second Embodiment]
[0047] In the first embodiment, the so-called double-tooth co-rotating scroll compressor
in which the walls are provided on both sides of each of the scroll members in the
axis direction has been described. In a second embodiment, a so-called single-tooth
co-rotating scroll compressor in which the wall is provided on one side in the axis
direction is described.
[0048] Fig. 5 illustrates a single-tooth co-rotating scroll compressor 1A. The co-rotating
scroll compressor 1A includes support members 20 and 22 that respectively support
a wall 7b of a driving-side scroll member 7 and a wall 9b of a driven-side scroll
member 9. Although Fig. 5 does not illustrate the vicinity of the motor 5 illustrated
in Fig. 1, the vicinity of the motor 5 has a similar configuration in the present
embodiment.
[0049] As illustrated in Fig. 5, the driving-side support member 20 is fixed to a front
end (free end) of the driving-side wall 7b of the driving-side scroll member 7 through
a positioning pin 41. The positioning pin 41 is fitted into the driving-side wall
7b in a non-pressed-in state while the positioning pin 41 is pressed into the driving-side
support member 20.
[0050] The driven-side scroll member 9 is sandwiched between the driving-side support member
20 and the driving-side scroll member 7. Accordingly, a driven-side end plate 9a is
disposed to face the driving-side support member 20.
[0051] The driving-side support member 20 includes a shaft portion 20a on center side. The
shaft portion 20a is rotatably attached to the housing 3 through a driving-side support
member bearing 26 that is a ball bearing. Accordingly, the driving-side support member
20 rotates around the driving-side rotation axis CL1 as with the driving-side scroll
member 7.
[0052] A pin-ring mechanism 15' is provided between the driving-side support member 20 and
the driven-side end plate 9a. More specifically, a ring member 15a is provided on
the driven-side end plate 9a, and a pin member 15b is provided on the driving-side
support member 20.
[0053] The driven-side support member 22 is fixed to a front end (free end) of the driven-side
wall 9b of the driven-side scroll member 9 through a positioning pin 41. The positioning
pin 41 is fitted into the driven-side wall 9b in a non-pressed-in state while the
positioning pin 41 is pressed into the driven-side support member 22.
[0054] The driving-side scroll member 7 is sandwiched between the driven-side support member
22 and the driven-side scroll member 9. Accordingly, a driving-side end plate 7a is
disposed to face the driven-side support member 22.
[0055] The driven-side support member 22 includes a shaft portion 22a on center side. The
shaft portion 22a is rotatably attached to the housing 3 through a driven-side support
member bearing 28 that is a ball bearing. Accordingly, the driven-side support member
22 rotates around the driven-side rotation axis CL2 as with the driven-side scroll
member 9.
[0056] The present embodiment achieves the following action effects.
[0057] The positioning pins 41 that perform positioning between the walls 7b and 9b and
the support members 20 and 22 are pressed into the support members 20 and 22 while
the positioning pins 41 are fitted into the walls 7b and 9b in the non-pressed-in
state. As a result, the positioning pins 41 can be firmly fixed to the support members
20 and 22, and fitting of the positioning pins 41 does not cause shape deformation
of the walls 7b and 9b. Therefore, there is no possibility of deterioration in performance
and durability of the co-rotating scroll compressor 1A because shape deformation does
not occur on the walls 7b and 9b as described above.
[0058] Note that, in the above-described embodiments, the co-rotating scroll compressor
is used as the supercharger; however, the present disclosure is not limited thereto.
The co-rotating scroll compressor is widely used to compress fluid, and for example,
can be used as a refrigerant compressor used in air conditioner. In addition, the
scroll compressor according to the present disclosure is applicable to an air brake
device using air force, as a brake system for a railway vehicle.
